The road around Regent Circus was closed for all of Sunday morning while details of the fight, believed to have involved about 15 men outside Dream Lounge, were established.

Three men in their early 20s have been arrested for grievous bodily harm and were taken into custody at Gablecross Police Station.

Forensic officers combed the scene, laying out evidence cones in a trail leading past the Dream Lounge towards the Gandhi restaurant.

A spokesman for Wiltshire Police said: “Police were called at 4.21am to the scene of a fight outside the Dream Lounge. The fight is believed to have involved 15 men, and one man received serious facial injuries and was taken to Great Western Hospital.

“Three men, all aged in their early 20s, were arrested on suspicion of grievous bodily harm and were taken to Gablecross police station where they remain in custody.

“Enquiries are continuing.

“Swindon CID are asking for any witnesses to contact them with information.”

A spokesman for South Western Ambulance Service said: “We were called at 4.23am to an incident outside the Dream Lounge on Regent Circus.

“We sent one rapid response vehicle and one ambulance unit. As a result we took one male patient to Great Western Hospital who had been bottled and suffered serious facial injuries.

“The injuries were quite severe as the patient was transferred straight to the resuscitation unit for unconscious patients.”

Pete Rogers, owner of the Dream Lounge, said: “I am currently helping police with their enquiries and cannot comment further. We will be opening as usual and are open as normal tonight [Sunday]. The Dream Lounge is not implicated in any way as the incident occurred outside. We will have to wait and see what comes out of the police investigation.”
